Computer System Architecture

The Von Neumann architecture is also known as the

• Cache memory

• Stored Program Concept

• Embedded System

• Fetch Decode Execute Cycle

The Program counter (PC) contains

• Address of current instruction

• Data to be executed

• Address of next instruction to be fetched

• the decoded instructions

The purpose of the Arithmetic Logic Unit (ALU) is to

• Store data

• Perform arithmetic and logical operations

• Control the flow of data

• Manage memory allocation

Which of the following is a characteristic of RISC architecture?

• Complex instruction set

• Large number of addressing modes

• Fixed instruction length

• Microprogrammed control

The main function of the Control Unit (CU) is to

• Execute instructions

• Fetch instructions from memory

• Direct the operation of the processor

• Store intermediate results

What is the primary advantage of using a RISC architecture over a CISC architecture?

• Higher instruction throughput

• More complex instructions

• Lower power consumption

• Greater memory usage

In a computer system, what does the term 'bus' refer to?

• A type of memory

• A communication system that transfers data

• A storage device

• A processing unit

An address bus is

• unidirectional

• Stores address signals

• Bidirectional

• carries address signals

Which of the following best describes the function of cache memory?

• To store permanent data

• To speed up data access for the CPU

• To manage network connections

• To execute complex algorithms

The factor of a CPU is affected by

• control bus

• clock speed

• cache memory size

• Core
